1. Prevent dig errors from corrupting host's /etc/hosts …

   It's possible for `dig` to print error messages and still succeed, such as
   if retries are attempted. If that happens, each word of the error
   message is treated as a separate IP for the service that's being
   resolved, causing /etc/hosts to be updated with garbage data.
   
   This PR does 2 things:
   - filters out error messages from `dig`, which always begin the line
     with ';' (usually with ';;', but some messages only have one
     semicolon)
   - sets maximum retries to 0 when using tcp for dns, so that the behavior
     matches that of udp
